長方形基礎の加振による半無限粘弾性地盤の振動特性(その2)

Abstract

In this paper, we investigate the vibrational behaviors of a visco-elastic ground subjectedto vertical and horizontal harmonic excitations on the rectangular surface area, by making useof the similar treatment in the previous paper. The numerical results of the amplitude and phasecharacteristics of the displacement in the parallel and perpendicular directions to each excitationare shown graphically along two principal axes of the rectangular area on the surface and alongthe depth below the center of the rectangular surface area. We discuss the effect of frequency ofexesting force, width of the base, distance from the center of the base and damping coefficient inthe ground upon the vibrational characteristics.
